SELENOS and asthma: We genotyped single nucleotide polymorphisms (SNPs): − 105/rs28665122 in SELS or SEPS1 (selenoprotein), three single nucleotide polymorphisms in IL18 (−105/rs360717, + 183/rs5744292 and + 1467/rs574456) and R501X/rs61816761 in FLG, the major locus associated with atopic dermatitis and predisposing to asthma, in a minimum of 6743 T1D cases and 7864 controls.
